Through block wall experimental study we can find out that cracks would appear late and the load of crack-resisting and limit-resisting are increased obviously by the constructional measures in the wall. It is very effective method that the splayed cracks are controlled by sill ring beam, the horizontal bending cracks are controlled by structural column on the side of the wall and the horizontal cracks on the top of the wall are controlled by the whole ring beam. It is the most effective method that wall cracks are controlled by structural column, crout column and sill ring beam.

通过试验主要得到在墙体中采取构造措施后，墙体裂缝推迟出现，开裂荷载和极限荷载都有很大程度的提高，同时发现窗台圈梁在控制窗角的八字缝、墙体两侧构造柱对于防止水平弯曲缝以及全截面的圈梁在防止墙体和圈梁交界处的裂缝的出现能起到很好的效果，通过试验确定在砌块墙体中采取&构造柱+芯柱+窗台圈梁&的构造措施来控制裂缝是最为经济合理有效的。

Results The expression of ADAM19 are mainly in the cell membrane, plasma and column of cytotrophoblast; The expression of ADAM19 is mainly located on cytotrophoblast during first trimester of pregnancy, and on syncytiotrophoblast in second and third trimester.

The ethanol extract was dissolved with HCl, the acidic extract was basified to pH9-10 with NH_3-water and extracted with CHCl_3 to give total alkaloids. five alkaloids were isolated with column chromatography and preparative thin-layer chromatography, and three of them were identified as dehydrocorydaline、 corynoline and dihydrosanguinarine on the basis of spectral analysis MS,~1H-NMR,~(13C-NMR and physicochemical properties. All of them were found for the first time from this plant.

为研究灰绿黄堇的化学成分，本文将灰绿黄堇乙醇提取物采取酸提取、碱游离后萃取的方法得到总生物碱，然后利用柱色谱、制备薄层色谱等方法分离、纯化了灰绿黄堇中5种生物碱，并利用IR、MS、~1H-NMR、~(13)C-NMR等方法鉴定了其中的3种，分别为去氢紫堇碱、紫堇灵、二氢血根碱，均为首次在此植物中发现。

本项目以西太平洋边缘中、深层水体为对象，利用微体古生物学、生物地球化学和年代学方法，通过对现代底栖有孔虫分布特征及其环境控制因子、柱状岩芯中底栖有孔虫属种和形态类型的分布特征、底层水体的温度及营养水平、各主要古环境演化事件时期浮游和底栖有孔虫14C年代学特征等主要内容的研究，综合探索了晚第四纪以来西太平洋边缘中层和深层水体的性质和流通状况的演化史。

Gingerols in ginger oleoresin were separated by AB8 macroporous adsorption resin and silica gel column chromatography. The samples were characterized by the gas chromatography-mass spectrometry method.The peak area normalization method was used to determine the relative percentage of the components and the rate of accumulation of gingerol was determined by contrasting with gingerol standard samples. The results showed that gingerols was concentrated on the 3rd and the 4th parts.
